Scottie Cramp is a low-severity neurological condition that can affect dogs of all ages and breeds. Scottie cramp is a hereditary episodic movement disorder in Scottish Terriers caused by a serotonin metabolism defect. Episodes of muscle over-contraction occur during excitement or exercise, causing abnormal gait and posture but no pain or loss of consciousness. It is documented across 1 breed, though prevalence and severity can differ significantly between them. It typically becomes apparent at 6 months - 3 years. Early signs to watch for include episodic arching of spine, overflexion of hindlimbs, somersaulting, and triggered by exercise or excitement. When treatment is required, costs are estimated at £100-£400/year depending on severity, location, and the specific intervention needed. Scottie Cramp has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
